What's wrong?
The 2017-2019 Fccc Mc motorhome chassis uses an air brake system with separate primary and secondary air circuits. The pressure gauges on the dash are supposed to show the air pressure in the matching circuit, so the driver can see whether each brake air supply is holding pressure.
On affected chassis, the plumbing for those gauge lines was routed according to an installation diagram with a discrepancy at the low air module. The primary air line was connected to the secondary air pressure gauge, and the secondary air line was connected to the primary air pressure gauge. That means the gauges show the opposite circuit, giving the driver misleading information about the brake air system.
There is no warning sign before failure. The gauge readings still appear on the dash, but they are assigned to the wrong air circuit, so the problem is not obvious from the driver's seat.
Who's affected?
Covers the Mc line across 3 model years, with each listed year tied to the same brake system component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
An air system failure can give the driver an incorrect pressure reading. That bad reading can confuse the driver and increase crash risk because the dashboard information no longer matches the air system's actual condition. Schedule the dealer inspection and correction soon. Repair is free at any franchised Fccc dealer.
What should I do?
- Check your VIN to confirm your 2017-2019 Fccc Mc chassis is included in this recall.
- Contact a franchised Fccc dealer to schedule the free air-gauge-line inspection that corrects swapped primary and secondary air pressure readings.
- Bring the recall notice if you received one. Reference recall number 18V677 and Fccc recall FL-793 when you call.
- Drive cautiously until the inspection is complete, since swapped air gauge lines can show the wrong brake-system pressure.
What happens at the repair
At the dealer, an Fccc technician inspects the air gauge lines to confirm the primary and secondary air lines feed the correct air pressure gauges. If the lines are crossed, the technician corrects the plumbing so each gauge reads the right brake air system. The inspection and correction are free under recall 18V677. Parts and labor are covered at Daimler Trucks North America authorized service facilities.
